Detection device for motor shaft

The invention relates to the technical field of motor accessory production equipment detection, and especially relates to a detection device for amotor shaft. The device comprises a detection workbench, a shaft supporting plate, a rotary clamping mechanism, equipment frames, a transverse flaw detection mechanism, a moving mechanism and a torque sensor. Three groups of equipment racks and fixing plates are arranged above the detection workbench, the transverse flaw detection mechanism and the moving mechanism are correspondingly arranged between the equipment frame and the fixing plate, the transverse flaw detection mechanism comprises a driving motor I, a first ball screw, a first connecting block, a first nut pair, a connecting rod and an ultrasonic flaw detector, and the driving motor I is fixedly connected with the first ball screw through a shaft coupling. According to the motor shaft detection device, through the arrangement of the detection device, the gyroscopic moment detection of the motor shaft and the nondestructive flaw detection of the motor shaft by using the ultrasonic detector are integrated in the same detection equipment, so that the use performance of the motor shaft detection device is improved.
